Abstract

For widespread distribution of layered foundation, deformation and bearing capacity are two important elements in engineering project, the calculating depth of additional stress must first be established in deformation computing. For structural features of layered foundation to explore the impact factors and variation of additional stress calculating depth, an integrated impact of soil structure, soil thickness and basis width on the calculating depth has been researched. It indicates that in two-layer foundation, the soft soil has a greater impact on the depth and the calculating depth will increase with the basis width increases, but which is the ratio of depth and basis width will reduce. Also, in multi-layered foundation, the overlying hard soil depth has little effect on the depth, depth and soft thickness with a negative correlation; with the base width increases, the calculating depth increases, presents a decreasing trend in a range. And addition, the deformation ratio method is proposed to determine the calculating depth of additional stress in multi-layered foundation which is with a obvious structure of layer.
